Abstract: 
An electronic newsletter was developed for the peppermint production regions in Oregon to assist growers and fieldmen to consider control of mint root borers, cutworms, armyworms and loopers during the growing season prior to crop damage. The newsletter was designed to help with timing of this new insecticide application strategy and to be used in conjunction with existing field monitoring/scouting programs. Extension Agents from the Willamette Valley and Union County were valuable cooperators and provided scouting services to confirm insect development model accuracy. A formal survey of those receiving the newsletter indicated 91 percent considered the weekly newsletter to be either very useful or somewhat useful.

Abstract: 
Two-spotted spider mites (TSSM) are an important pest on hybrid carrot seed production in central Oregon. Predator mites have been used to successfully control TSSM in peppermint production in central. This preliminary project was conducted to determine if there is potential for the use of predator mites in carrots. Circumstantial evidence from the results suggests predator mites were successfully established, they were successful in reducing TSSM populations, they were able to effectively disperse throughout the field, predators can be introduced in the fields with moderate amounts of TSSM and they may be able to keep populations at a commercially acceptable level.

Abstract: 
An electronic newsletter was developed for the peppermint production regions in Oregon to assist growers and fieldmen consider control of mint root borers, cutworms, armyworms and loopers during the growing season prior to crop damage. The newsletter was designed as a two-year project to help with timing of this new insecticide application strategy, and to be used in conjunction with existing field monitoring programs. Extension Agents from the Willamette Valley and Union County were valuable cooperators and provided scouting services to confirm insect development model accuracy. A formal survey of those receiving the newsletter indicates that the newsletter was well received, provided information valuable to growers and crop consultants/scouts, and respondents would overwhelmingly like to see the newsletter continue.

Abstract: 
Two-spotted spider mites (TSSM) are an important pest on hybrid carrot seed production in central Oregon. Predator mites have been used to successfully control TSSM in peppermint production in central Oregon and a preliminary project on carrots grown for seed conducted in 2014 indicated that there is potential for use of predator mites in carrots. Results from 2015 indicate that predator mites were successfully established at all locations in non-Zeal and Zeal-treated plots, the combination of Zeal and predator mites held TSSM populations below the treatment threshold, while the late application of predators alone was unable to keep TSSM populations in check in the non-Zeal plots.

Electronic Mint Pest Alert Newsletter Regarding Control of Mint Root Borer, Cutworm Complex and Loopers (Year 3)

Series/Report number: 
COARC2016
Abstract: 
An electronic newsletter was developed for the peppermint production regions in Oregon to assist growers and fieldmen consider control of mint root borers, cutworms, armyworms and loopers during the growing season prior to crop damage. Recommendations of optimal insecticide application timing were based on the insect development models, and were provided through weekly e-Newsletters in each region from mid-June until the end of July. Extension Agents from the Willamette Valley, Central Oregon, and Union County provided scouting services to confirm insect development model accuracy. A formal survey of those receiving the newsletter indicates that the newsletter was well received, provided information valuable to growers and crop consultants, and respondents would all like to see the newsletter continue.
